Specification of Letters Patent.

Fatented Jan. 8, 1918.

Application filed April 17, 1916. Serial No. 91,705.

To all 'whom t may concern:

Be it known that I, ARCHIE D. CoALsoN, a citizen of the United States,residing at Birmingham, in the county of Jefferson and State of Alabama,have invented a new and useful Frog, of which the following is aspecification.

This invention relates to railroad frogs, one object being to provide aremovable point which, when worn, can be replaced by a new one, therebyavoiding the expensive renewal of the entire frog which has heretoforebeen necessary when the point has bef '001118 WOII).

A. further object is to provide simple and efficient means for holdingthe point firmly in position so that there is"` no danger of its workingloose.

lfVith the foregoing and other objects in view which will appear as thedescription proceeds, the inventlon resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that changes in/'the preciseembodiment of the invention herein disclosed, can be made within' thescope of what is claimed, without departing from the spirit of theinvention.

In the accompanying drawin s the preferred form of the invention hasgeen shown.

In said/drawings Figure'l is a plan vlew of a frog embodying the presentimprovements, portions of rails being shown connected thereto.

Fig. 2 is a central longitudinal section through the frog. q

Fig. 3 is an enlarged section on line A-B Fig. 1. I

Fig. 4.- is an enlarged sectionon line Fig. 1.

Fig. 5 is an enlarged section on line\E-F Fig. 1.

Fig. 6 is an enlarged section on line G- 1. Fig. 7 is a plan view of theremovable point.

Referring to the figures by characters of reference l and 2 deslgnatediverging wing rails and diver-ging i'rom the inner ends of these wingrails are flanges' and 4.' A substantially horizontal web 5 isinterposed between and formed integral with the wing rails and theflanges and forms the bottom of the channel provided between the wingrails and lianges for the receptionv of the flanges of the rar wheelsThat portion of formed with yopenings 7 and the walls of the depresslonare preferably provided with longitudinal ygrooves 8 overhung by theadjacent upper portlons of the web 5. The 0pposed grooves 8 are designedto receive flanges 9 extending along the sides of a wedge-shaped point10 which, when thrust longitudinally Within the depression 6 will fitsnugly therein with its apex projecting upwardly from the apex of thedepression. The base of the point rests on the bottom of the depressionG as shown particularly in Fig. 1 and the top of the point is obviouslydisposed in the same plane as the tops of the wing rails 1 and 2 and theflanges 3 and 4. That portion of vthe point located beyond the web 5 isshaped to lie fiush with the bottom of the remainlng port-ion of thefrog. This projecting portion of the point has base flanges 11 which maybe secured to a cross tie by spikes in the usual manner. A tongue 12 isextendedfrom the end of the frog point, and the sides of this tonguearefparallel with the sides of the point. Longitudinal grooves 13 areformed along the upper edges of the sides of the tongue 12 and are' thetop of the oint. The rails are fastened to the tongue y means of bolts16 extending transversely through the webs of the rallsand through theton ue 12.

'Basel fian'ges 1,7 exten outwardly from the "wingrrwltilsl and 2 andfrom the flanges 3 and 4 and also extend across the outer ends oftheflanges 3 and 4 and lup to the sides of the oint 10. lThe inner sides ofthe wing rails 1 and 2 are out away longitudinally as at 18 to receivethe outer sides of the heads of rails 1S). These rails are fastened tothe wing rails by means of bolts 20 in the usual manner. Base ianges 2lare preferably provided along the inner sides of the wing rails and atthe adjacent end of the web 5 and are adapted to aline with the(-orresjmlnling 'base flanges of the rails 1.9,'

Obviously when the point 10 becomes Worn it can be removed simply bydetaehing vrails 14 from the tongue 12 and then Withdrawing the pointlongitudinally from theyA de ression 6.

he rails 14 are to be provided with fish plates 22 which lap and aresecured to the i' ,sides of the point 10, recesses 23 being pro- "lo A ithrough the wing rai s and flanges, an integral web connectmgtheame andhaving a V-shaped including oppositely diverging ganarme depressionbetween the flanges, there being longitudinal grooves in the Walls ofthe depression, and a point insertihle llongitudinally into thedepression, flanges on the point adapted to enter the grooves, andflanges on the point adapted to seat on and for attahment to the ties.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature inthe presence of two Witnesses.
